"Bought the starter package as my first gun, not knowing much about it. The gun has grown with me and is a great baseline for someone looking to get into airsoft and wants some room to add attachments to their gun, or upgrade down the road.

Pros:
- Very Light but also quite durable
- Easy to maintain and work on (many youtube videos on how to take M4's apart)
- Many places to add attachments (M-LOK and Picatinny rails)
- Good gearbox right out of the box
- Quick change spring system for change of fps
- Adjustable Hop-up
- LOTS of battery space, (Personally running a 11.1v and still have plenty of space for wires and the battery)

Cons:
- Can't add a 2-point sling
- Comes with only one Magazine, and it's a Hi-Cap Magazine (not a problem for some)
- Finding inner barrel's are quite expensive or hard to find

I have never regretted this purchase, and would highly recommend and endorse it. In my humble opinion, if you’re looking for an upgradable M4 with some bells and whistles right out of the box, this is one of the best you can get. Hope this review helped you make an informed purchase!

"I bought this gun as an extra for people to use. I have tested it out every couple months. It shoots very consistent and hits the target outdoors at a measured 50yards with ease using .28gram BBs. I opened up the gearbox because somehow when someone was borrowing it managed to get a couple BBs inside the gearbox and jammed the gun up. Maybe taking mags in and out upside down?? Anyway, when I opened the gearbox I was very impressed with the internals. The gears appeared to be quality steel. The piston had all metal teeth! Some lubricant was on the gears, but not much at all, so it was not all gunked up, which was nice. The wires seemed to have very nice protective coating. And once I cleaned the broken BBs out, it shot perfectly fine again. Also it has a rotary hop-up unit. The gun is sturdy and lightweight, just take care of it and not throw it around and dropping it and it should last a good while.
I have not tried 11.1 lipo in it…but 7.4 and 9.6 seem to work great.
Just remember, quality BBs helps any gun out!

"This aeg is great so far good range and rail space for attachments, I run a red dot and a vertical grip. Overall it’s light and maneuverable but doesn’t feel cheap and plasticity. The only thing bad about it is how it doesn’t come with compatibility for a 2 point sling, (being one attachment point at the back of the receiver and one on the barrel) still can use a one point sling fine though.
